I worked for UPS in the IT department and ALL of the trucks were hooked up with every single new technology. UPS came into the computer technology business with a huge bang. The trucks can tell how hard a driver pressed on the brakes (data at the time used for maintenance purposes only), it automatically timed how long a driver was out of the truck (again for timecard purposes).
The 18 wheeler trucks are used in a very interesting way too. One truck meets another truck, each with a load, switch drivers and on to the next destination, no long haul drivers so to speak. I wonder if this is a normal practice within the trucking industry or just a UPS thing using all the latest technology. Those trucks are loaded with data gathering information which is then uploaded to stations that is then used for multiple tasks, including package information, and the amount of soap that is used on each truck when washed each day.
Your larger companies all have these things. Some are monitored by qualcom others by peoplenet. Way different programs but pretty much the same output of information.
Trucker lingo for companies like UPS and FedEx who do the point to point job you describe where one truck meets another truck then goes back where is came from is referred to as freight haulers. For instance I have longtime friends who haul for fedex. They start in Memphis each day, travel I-40 going east and meet another team driven truck in eastern tennessee, swap trailers and go back to Memphis and do it all over again. Some of the freight hauling companies are now defunct but back in the day you had recognizable names such as old dominion and humping to please with the camel logo. UPS and FedEx are used mostly for very fast delivery which drives up delivery price. Naturally they get paid more for the expedited services.
Car parts are moved very much the same way utilizing a timed system and are under contract with companies such as ryder, Ryder is much more than rental moving trucks. They have many divisions including their own brokerage company.
The newer model rigs themselves are amazing. Just a example I'm pretty versed in currently is a volvo. (Other brands have this technology as well) My spouse has a 2016 model volvo, it has its own, from the factory built in computer system that when it finds a fault code, it's sends information back to Volvo and it diagnoses itself. This also sends an alert to the companies shop manager. It's very detailed. It can tell them most anything and if it's a programming issue the tech at volvo can send signal back to the truck and download a fix. It's truly amazing.
Then on top.of the truck itself the company has a computer installed tjat recognizes a trailer identification when it's hooked to the tractor. No need for the driver to call in or send s computer message stating they picked up trailer number xyz000.
Logging is done by the computer as well eliminating the need for paper logs and reduces errors. A driver is only allowed to driver 11 hours within a 14 hour period and must take a 30 minute break within the first 6 hours of driving. When it's coming time for the driver to take a break the computer will alert the driver he or she needs to be looking for a place to satisfy his or her 30 minute required break. When he or she starts the break he or she taps a macro button on screen to let the computer know he or she is following the rule. If the driver is nearing his or her 11 or 14 hours, a hour before the deadline, the computer alerts the driver so tjey know to be looking for a place to bed down for the night to complete their required 10 hours of combined off duty and sleep time period.
Now I am not sure how all companies with this technology operate but in the case of my spouse, he is given a report, I want to believe it is quarterly, and in that report it will tell him how many times he's had a hard breaking, if he's gone over speed (the truck is governed but weight pushes you downhill allowing you to speed) it tells if and how many times he's gone over his drive time. It is a big no-no to go over drove time but certain conditions allow it for a shirt period such as bad weather. Say it's snowing and your either stuck on the interstate at a standstill or moving 10mph, you cannot just shut down on the highway. You are allowed to go over you log time only long enough to get the tractor and trailer parked in a safe manner off the highway.
These computers are a excellent tool. Think black box... They can tell a lot about wjat has happened in the event of a crash. This has saved millions of dollars in insurance claims.
